INTRODUCTION

2.1 General

Wise HP33-series AVR is a 3 phase 4 wire automatic voltage regulator or stabilizer which each phase is

controlled independently by servo motor or also called "3 phase 4 wire independent phase control". Wise

HP33-series AVR supplies pure sine wave output with low harmonic distortion. It has LED display and LCD

screen to display operating status and electrical data and audible alarm to alarm when the AVR has faults.

2.2 Features

- 3 phase 4 wire independent phase control

- Pure sine wave output

- Overload and short circuit protection

- Automatic shut down when main electricity supply is abnormal

- Easy installation

- Surge protection

- Display operating status and electrical data via LED display and LCD screen

- Volt meter and Amp meter

- EMI/RFI filter or noise filter (Option)

2.3 Principle

Normal operation mode: Wise HP33-series AVR takes power from main electricity supply. Then, the

current flows to automatic voltage regulator (AVR) circuit to regulate the voltage level. This process is

controlled by servo motor. If the voltage is too high or too low, the AVR circuit will regulate it to the level that

is safe for the loads. Then, flows to EMI/RFI noise filter circuit (option) and check load level at Power watcher to

protect overload. If the AVR is overloaded, it will alarm. You have to disconnect some loads. If the AVR is under

these situations; output over/under voltage, overload, input frequency fault, over temperature (option), and

etc., it will shut itself down and restart automatically when it returns to normal (for automatic restart mode

only).

Maintenance bypass mode: When the AVR is stop and disconnected from main electricity supply for

maintenance, user turns off the INPUT BREAKER and turns MAINTENANCE BYPASS/AVR SELECTOR SWITCH to

position "2" (select maintenance bypass mode), the loads will take power directly from main electricity supply.

Note: There are 2 restart modes (automatic and manual restart). After the AVR shuts down and the restart

mode is manual, once it detects no more faults, it will alarm. You can restart the AVR by pressing

simultaneously once.
